Autoimmune diseases occur with greater frequency in women than in men, suggesting that the mechanism of pathogenesis is conditioned by gender. So far not defined clearly factors responsible for the development and course of these diseases depending on sex. However, it was found there is a clear sexual dimorphism of the immune system, which may determine the process of autoimmunity. The causes of the increased incidence of women in autoimmune diseases are attributed to the action of the hormones estrogen, which can promote the process of autoimmunity and enhance the clinical symptoms of the disease. As shown sex hormones have immunomodulatory activities on dendritic cells, macrophages, neutrophils, B and T cells. In the both situation the response to strange antigens and mechanism of autoimmunity sex hormones have been shown to play contributory roles in process of cytokine production, the expression of cytokine receptors and response of effector cells. According to recent research, the development of autoimmune diseases is determined by genetic factors. Changes in the autosomal genes X and Y chromosomes play an important role in the progression of autoimmune processes, especially that the X chromosome has genes responsible for the regulation of the immune system.
自身免疫性疾病在女性中的发生率高于男性,这表明发病机制受性别影响。迄今为止,尚未明确取决于性别的这些疾病发生和发展的因素。然而,已发现免疫系统存在明显的性别二态性,这可能决定自身免疫过程。女性自身免疫性疾病发病率增加的原因归因于雌激素的作用,雌激素可促进自身免疫过程并加重疾病的临床症状。研究表明,性激素对树突状细胞、巨噬细胞、中性粒细胞、B细胞和T细胞具有免疫调节活性。在这两种情况下,性激素在针对外来抗原的反应和自身免疫机制中,均已显示在细胞因子产生过程、细胞因子受体表达及效应细胞反应中发挥作用。根据最近的研究,自身免疫性疾病的发展由遗传因素决定。常染色体X和Y染色体的变化在自身免疫过程进展中起重要作用,尤其是X染色体具有负责调节免疫系统的基因。
